Why Is Super Micro Computer Stock Surging on Thursday?

Super Micro Computer Inc. (NASDAQ: SMCI ) stock is trading higher on Thursday as the company gave stock investors an unexpected update on Tuesday after stating that fourth-quarter revenue is expected "near the low end" of its guided range of $11 billion to $12.5 billion.

The Nasdaq is down 2.26% while the S&P 500 has shed 1.35%.

Stock traders focused instead on preliminary gross margins of 15% to 17%, up from previous guidance of 8.2% to 8.4%, and "more than $60 billion" in new AI infrastructure orders.

Super Micro Computer challenged those metrics by delivering higher profitability despite forecasting lower-end revenue.

Management attributed the higher gross margins to a "favorable customer and product mix," indicating customers are purchasing richer AI system configurations.

Product mix improvements signal potential pricing power and stronger demand for premium offerings alongside a record order pipeline.

Technical Analysis SMCI is trying to stabilize after a steep 12-month slide of 39.69%, and today’s push has the stock trading 12.2% above its 20-day SMA ($27.75), a sign the near-term trend has improved.

The bigger picture is still mixed-to-bearish because it remains 5% below its 50-day SMA ($32.79) and 7.3% below its 200-day SMA ($33.59).

Key Resistance: $36.50 — a nearby ceiling where rebounds can stall, sitting above the 50-day and 200-day moving averages that the stock still needs to reclaim Key Support: $25.50 — a nearby floor tied to a prior buyer-defense zone, and it’s also below the 20-day average where a failed rebound could retest Super Micro Computer Stock Short Interest Report Short interest in Super Micro Computer increased during the last reporting period, rising from 96.23 million to 103.19 million.
